A fossil-rich block of rock from the famed Coelophysis Quarry at Ghost Ranch, New Mexico, housed in the Vertebrate Paleontology collection at Carnegie Museum of Natural History (Pittsburgh, Pennsylvania). Collected by Museum paleontologist Dr. David Berman and his colleagues in the early 1980s, this block contains numerous Late Triassic (~205 million-year-old) fossils, most of which belong to the small-bodied carnivorous dinosaur Coelophysis bauri. A beautifully-preserved skull of Coelophysis is visible towards the lower right of the image.
